> Considering that markets exist whenever 2 or more individuals gather
In the most general sense of "market", this is not wrong. However, you're talking from the point of view of a rather specific market theory. That market theory is not a fundamental force, it's just one of many ways of doing things.
It also has a very narrow definition of "fair", which makes sense within its own world, but I would argue is not generalizable outside of that world.
